Problems solved by technology

In addition, since the heaving winch also needs to overcome the spring force of the powerful coil spring to lower the pantograph, a large winch is also required.
In addition, since the pantograph is pressed against the trolley wire with a strong spring, the pressing force tends to become excessive

Embodiment 1

[0031] use Figure 1 to Figure 11 Embodiment 1 of the pantograph device of the trolley truck of the present invention will be described.

[0032] figure 1 It is a schematic diagram of the overall structure of the trolley truck applied to Embodiment 1 of the present invention.

[0033] In this embodiment, a wire-type dump truck used for ore transportation and the like in a large-scale mine will be described.

[0034] exist figure 1 Among them, the reference numeral 1 is an overhead line (overhead wire) erected on the driving route of the mine, and the reference numeral 2 is a wire-type dump truck. An electrically driven dump truck running in any one of modes, in the overhead line mode, the dump truck 2 runs with electric power obtained from the overhead line 1, and in the non-overhead mode Among them, the dump truck 2 travels with the electric power obtained by driving the generator with the engine. In the present embodiment, the structure is adopted to travel in the troll...

Abstract

A pantograph device for a trolley truck includes: a bottom frame (6); a lower frame (8) mounted on the bottom frame in a swingable manner; an upper frame (10) swingable via a connecting shaft (9). installed near the front end of the lower frame; collector shoes (5), which are supported in a swingable manner near the front end of the upper frame; hydraulic cylinders (14), which are installed on the bottom frame, and are used to use The lower frame undulates; one end side of the spring (15) is connected to the bottom frame side, and the other end side is connected to the base end side of the upper frame. The spring (15) rotates the upper frame upwards through the connecting shaft, and the pantograph The device is configured to rotate the upper frame upward via the coupling shaft by raising the lower frame with the hydraulic cylinder to increase the tension generated in the spring. Thereby, a large movable range can be obtained without using a long and strong spring, and the followability to the trolley wire can be improved without increasing the pressing force.

Description

technical field [0001] The present invention relates to a pantograph device of a trolley truck used for ore transportation in large-scale mines, and is particularly preferably a trolley dump truck capable of running in any mode of a trolley mode and a non-tieline mode In the wire mode, the wire type dump truck travels by the power obtained from the overhead wire, and in the non wire mode, the wire type dump truck does not obtain power from the overhead wire Electric power, that is, electric power obtained by driving a generator with an engine, etc. for traveling. Background technique [0002] Examples of pantograph devices for trolley trucks include devices described in JP-A-63-35102 (Patent Document 1), JP-A 2002-67776 (Patent Document 2), and the like. [0003] In the above-mentioned Patent Document 1, a dump truck used in ore transportation in large-scale mines is described, and it is described that in the non-stretch mode, it is driven by a generator driven by an engine...
